Its technical scheme is: mainly be made up of base, preceding horse head, axis, support, walking beam and balance weight, the afterbody of described walking beam is installed the back horse head, counterweight bucket of its below lifting, by back horse head and counterweight bucket Compositional balance system, by in the counterweight bucket, installing or extract liquid additional, realize not shutting down and accurate balancing; Remove former gearbox and drive motors, one cover Hydraulic Station is installed on its position, on the both sides of support and walking beam, install forward and backward hydraulic cylinder and forward and backward hydraulic stem additional, described forward and backward hydraulic cylinder links to each other with Hydraulic Station by hydraulic hose, by Hydraulic Station, forward and backward hydraulic cylinder and forward and backward hydraulic stem are formed dynamical system, under hydraulic action, drive the work done that moves up and down of walking beam and horse head by the forward and backward hydraulic stem in the dynamical system, direction is opposite because the impulse stroke of two cylinder design is identical, thereby reduced the load of Hydraulic Station, reduced the consumption of power.
Be provided with reversal valve in the above-mentioned Hydraulic Station, reversal valve is provided with fluid power A end and fluid power B end, and the preceding hydraulic cylinder of described dynamical system is connected with fluid power B end with fluid power A end by hydraulic hose respectively with the back hydraulic cylinder.
Install liquid additional in the above-mentioned counterweight bucket, and be provided with by-pass valve control.
Detailed scheme is that described counterweight bucket is the concrete prefabricated counterweight bucket of cylindrical hollow, and the inner bag of hollow can pass through the water filling inward of one way valve fast joint, or outwards discharges water by discharging valve, and air vent is in order to the balance inside and outside differential pressure.And the below of counterweight bucket is provided with protective screening, and the personnel that can prevent are strayed into and are subjected to unexpected injury.
Above-mentioned preceding horse head connects polished rod through the front overhang rope, drives polished rod and does work in well head.
Be connected with forward and backward hydraulic stem by guide bearing on the both sides of support and the walking beam.
Beneficial effect of the present invention is as follows: (1) power consumption significantly reduces, and has saved the energy; (2) compact conformation is simple, has reduced cost; (3) component have without spin increased safety; (4) accurate balancing, and need not shut down; (5) brake is simple, and it is easy to play machine, can not turn over machine; (6) simple, the wide ranges of jig frequency adjustment.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Among the last figure: 1-well head; 2-polished rod; 3-front overhang rope; 4-preceding horse head; 5-guide bearing; 6-preceding hydraulic stem;
7-preceding hydraulic cylinder; 8-axis; 9-support; 10-walking beam; 11-back horse head; 12-rear overhang rope; 13-air vent; 14-counterweight bucket; 15-protective screening; 16-one way valve fast joint; 17-discharging valve; 18-base; 19-back hydraulic stem; 20-back hydraulic cylinder; 21-hydraulic hose; 22-fluid power A end, 23-reversal valve; 24-fluid power B end, 25-Hydraulic Station.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the invention will be further described:
Well head 1 of the present invention, polished rod 2, front overhang rope 3, preceding horse head 4, walking beam 10, axis 8 and support 9, base 18 are all identical with former trip fine strain of millet formula oil pumper; The power of former machine, deceleration, balance, transmission device are removed; Between the front and back of its support 9 and walking beam 10 respectively symmetry install a pair of double acting hydraulic means promptly before hydraulic stem 6, preceding hydraulic cylinder 7 and back hydraulic stem 19, after hydraulic cylinder 20, and the fluid power A end 22 by reversal valve 20 in hydraulic hose 21 and the newly-increased Hydraulic Station 25 is connected with fluid power B end 24 respectively, forms dynamical system; Horse head 11 after the afterbody of trip fine strain of millet 10 newly installs one additional again, and the concrete prefabricated counterweight bucket 14 Compositional balance systems by a cylindrical hollow of rear overhang rope 12 lifting, the inner bag of hollow can pass through one way valve fast joint 16 water filling inward or other liquid, or outwards discharge water by discharging valve 17, air vent 13 is in order to the balance inside and outside differential pressure; Protective screening 15 can prevent that personnel are strayed into and be subjected to unexpected injury.
Specify the course of work of the present invention below in conjunction with accompanying drawing, as shown be static map of the present invention, connect power initiation Hydraulic Station 25 during work, under the effect of reversal valve 23, hydraulic oil conducts hydraulic oils to two double acting hydraulic cylinders through fluid power A end 22 respectively by hydraulic hose 21, because intersecting, the inlet opening up and down of two double acting hydraulic cylinders links to each other, before hydraulic stem 6 hydraulic cylinder 7 is outer forward stretches out the retraction acting in the hydraulic cylinder 20 backward of acting, back hydraulic stem 19, horse head 4 and back horse head 11 were done downward and the movement in a curve that makes progress respectively before trip fine strain of millet 10 drove around axis 8; Two unnecessary hydraulic oil of hydraulic cylinder flow back to Hydraulic Station 25 through hydraulic hose 21 by fluid power B end 24 simultaneously; When current horse head 4 arrives top dead centre, the reversal valve 23 of Hydraulic Station 25 switches hydraulic directio, at this moment, preceding hydraulic stem 6 shrinks in the hydraulic cylinder 7 forward, back hydraulic stem 19 is hydraulic cylinder 20 outer stretching out backward, the front and back horse head is done reverse movement in a curve, and four guide bearings 5 can be according to the fit angle of the automatic regulator solution pressure device of the angle of camber line; Motion and so forth, horse head 4 does work in well head 1 through front overhang rope 3 drive polished rods 2 before making; Owing to adopt closed hydraulic system, energy is fully utilized, thereby has saved the energy, when shutting down,, thereby kept hydraulic system relatively stable owing to pressure can not discharge in any position, saved the brake system of complicated rapid wear; It is the oil pumper counterweight that back horse head 11 connects counterweight bucket 14 by outstanding rope 12; During balancing, but the water filling in the courage of counterweight bucket 14 of one way valve fast joint 16 external hoses, or outwards discharge water by discharging valve 17, reach accurate increase and decrease counterweight to realize not shutting down the purpose of balancing by the increase and decrease water yield.
